BUSHING STRUCTURE,

Application led November 27, 1925, Serial No; 71,781.

My invention relates bers, 'such to sheet metal mema's the heads or other wall portions of metallic barrels or containers,

though the invention is not to Abe thus limited, and which are provided" with rims that enclose bushings,

these bushings in the case of barrels or other containers being provided to receive bungs or Stoppers and being usually interiorly threaded in` order that the same.

My sion ofs bungs ymay be screwed into the invention has for its object the provi-V an improved construction of the rim -portions of such sheet\ metal members and the bushings whereby these two elements may surrounded thereby, be so locked that the bushings'may not be turned and thereby disturb the fluid-tight assembly of the bushings. andrims.

In carrying Aout my invention, the rim upon 4the sheetv metal bodymember is outwardly bulged preferably from its unattached edge ,toward its attached edge and the bushing is formed with a body por# tion'. which is surrounded by the rim and one and preferablyl 'tions upon tion. Where two returned porthe exterior of its body porat -least two returned bushing portions are employed, one is receivedl 1n the recess formed by the bulging of the rim and the other is upon the rim being received between this rim,

the exterior of the latter returned portion and the body portion of the bushing.v ofthe bushing engage The returned portions the bulged portion of the rim and thereby hold the bushing from rotation.y l

.The invention will be more fully explained invcon'nection. with the accompanying drawings in which Fig. 1 is a` plan view illustratingy a construction of my invention,

bead 4 which margins the attached portiona of the rim. Saidrim thus-surrounds a -genf era-lly circular opening formed through the sheet metal member to permit of the passage of one place'as indicated in Fig. 8 and at a number Iof places as indicated'in Figs. 2 to 6 inclusive, the bulging 'extending from the unattached edge of the rim toward its at' tached edge and preferably only to the rim portionor portions 6 which margin the at.-v tached edge of the rim, adjacent lthe bead 4. A recess 7 is thus formed wherever the rim is bulged as described, each recess b'eing open, prior to the assembly of the'bushing with the lsheet metal member,-for the v reception of a returned portion of the bushing, as will presently appear.

The bushing is preferably interiorly threaded as indicated' at 9, this body portion being surrounded byl the rimand having as many re turned portions 10 as there Iare recesses 7 fluid or material through said mem- The rim is outwardly bulged at 5 at has a body portion 8 which' and which are' received 'in said recesses, be-f., ing passed theremto as the bushmg-ismserted into the rim from the unattached edge of the rim towardthe'attached edge of The returned bushing portion received l1n j each recess desirably substantially fills the recess so as to engage. not only the outer.

arcuate wall df the recess but also the end 'falls' of the recess that are transverse to the rim, these transverse walls of the recess and the returned portion of the bushing cooperating to prevent the bushing from turning. The bushing is desirably also provided with as many additional returned portions l1 as there are returned portions 10, the structure of Fig. 8 having one such returned ving the portions 6 vportions 12 of the bore of' the `remaining .figures has four such returned portions 11 alternating with-the yfour re- 'turned portions 10. Each returned portion 11 is upn the exterior of the rim, the rim being between this returned bushing portion Ao and the body portion "8 of the bushing. Each returnedn bushing portion desirably iills the gap between the transverse recess walls on the rim between which such returned portion l1 is disposed, -whereby rotation of the bushing with respect to the rim is further guarded against. The returned bushing portions upon the interior and exterior of the rim are in close contact with the rim to guard against any transverse movement vof Athe bushing with respect to the riml and to make the union between the rimfr and bushing fluid-tight,` the body pori tion of the bushing engaging the interior surface of the rim, where unrecessed, includof the rim and snugly fitting the same to guard against leakage. The fluid-tight union between the rim and bushing is furthered by the engagement of the unattached edge of the rim with the base returned bushing portions 11 that join these bushing portions with the bushing body 8. -It is obvious that many of. the advantages of my construction may be retained with the returned portions upon the exterior of'the rim or the returned portions upon the interior of the rim eliminated. Y

The bung or stopper 13 is received in the bushing. If the bushing isy i'nteriorly threaded, the bung is correspondingly threaded and has a polygonal formation 14, whereby a wrench may be applied thereto to screw it tightly into place. A sealing gasket 15 may be interposed between a flange 16 on the bung and the bead 4 and also to overliethe Hange 17 formed at the of the bushing,

end of the bushing `opposite theend from which the returned portions 10 and 1'1 spring. The' fiange .'17 desirably overlies the `unattached ends of the returned portions 11 the circular portion 18 of the sheet metal body member 1 being desirably closely gripped between theoian'ge 17 andthe returned bushing' portions 11 to' -ei'ect afurther Huid-tight connection between the bushing and the sheet 4metal memer. y

Changes may be fromthe invention.
